IMPROVEMENT |N OIL-CANS.

Specification forming part of Letters Patent No. 209,037, dated October15, 1878 application filed March 7, 1878. I

To all whom it may concern:

Be it known that I, ADDISON E. GARDNER,

of Milan, in the county of Washtenaw and State of Michigan, haveinvented an Improvement in Oil-Cans, of which the following is aspecification v The nature of my invention relates to an improvement inthe construction of oil-cans; and it consists in providing the can witha peculiar vent-pipe, which is doubled. upon itself near its center, andenters the can at the top of the same, one part of the pipe being insideof the can, with its open end near the bottom thereof, while the otherleg of the pipe is entirely outside of the can, and terminates near itsbottom, so that air will be admitted to the space at the bottom of thecan while liquid is being poured from the same.

In the drawing, which represents my invention in perspective, with aportion broken away to show interior arrangements, A represents anoil-can provided with the usual delivery-spout B, which, in turn, may beprovided with a stopper, 0.

In the side of the can I cut a slot, to, back of which, and within thecan, is properly secured aglass tube, D, as shown, open at both ends.This tube may be graduated as may be desired, or as the various sizes ofcans may require, to show how much liquid the can contains. Ifpreferred, the graduations may be made upon the outside of the can. Inthe top of the can is secured a funnelshaped neck adapted to receive acork or stopper. In the can at the side opposite to that in which thedelivery-spout is secured I secure a vent-pipe, E. This vent-pipe ismade from a single small tube, which is bent upon itself at or near itscenter, and forms two legs or parts, a a, which may be of equal length;but the part a is preferably somewhat longer than the other, as shown.The leg at is passed through the top of the can, and projects down nearthe bottom of the same and close to the side of the can opposite to thespout, while the other leg, a,

just where the open end of the inner part ofthe vent-pipe terminates,and by this form of vent-pipe the pouring of the liquid is facilitatedeven when the can is quite full.

The inner part of the vent-tube, projecting down into the liquid, willbecome partly filled with the oil, and when the can is tipped the oilwill flow in this tube toward the bend in the same and into its outerpart, a; but as soon as a vacuum is formed in the can the heavy weightof the whole body of oil in the can as compared to the very smallquantity in the vent-pipe will create a sufficiently-perfect vacuum tocause the oil in the vent-pipe to be driven into the can byair-pressure, and the can to be automatically vented.

By this construction of can the person filling the same can at all timessee how much liquid has been poured in by looking at the graduated gage,while the funnel-shaped neck greatly assists in the operation.

When it becomes necessary to pour from the can the cork or stopper doesnot have to be removed for venting, as air finds ingress into the canthrough the vent-pipe.

What I claim as my invention is- The vent-pipe E for oil-cans, bent uponitself into two parallel parts, a a, the part a being entered into thetop of the can on the side opposite to the delivery-spout, andterminating near the bottom and close to the side of the can,constructed and arranged substantially as described and shown.
